So, I must ask...
How do you determine what something is worth, if the existing auction databases are skewed too high?
Retail prices from major sellers always seem to be even higher, as are buy it now items on ebay. Are we talking the price you get from selling to a dealer or consigning to an auction? If so, there is always a gap.
By definition, any item you just bought is worth more TO YOU than to anyone else. Unless you can widen your potential audience you will lose money on the resale. By the same logic, any auction you lose ended up overpriced.
Fair questions and points.
'Value' is always what a particular poster is worth to a particular person in terms of how much it sold for, anywhere....but more broadly an estimated price after all recent sales including ebay is taken into consideration. There is no real math behind it. However, many posters (most, not counting stuff you never really see more than once or twice in a lifetime) will always go for more in auction houses such as eMovie, HA, etc.
The comment to Bruce is more to point out that he gets more on a Dragon's Lair poster than Joe Schmoe would on ebay, craigslist, etc...because he is eBruce, which is THE point, not what Dragon's Lair is 'worth'. Good for Bruce to be sure, but when he sells Indy Last Crusade posters for over $100 if not much more a pop when they go for pennies on the dollar on ebay, they sure as heck aren't worth what Bruce gets, except to that particular buyer for whatever reason, the experience and trust with eMovie, ignorance, laziness, whatever.
